PyAMF provides Action Message Format (AMF) support for Python that is compatible with the Adobe Flash Player. It includes integration with Python Web frameworks like Django, Pylons, Twisted, SQLAlchemy, and more. The Adobe Integrated Runtime and Adobe Flash Player use AMF to communicate between an application and a remote server. AMF encodes remote procedure calls (RPC) into a compact binary representation that can be transferred over HTTP/HTTPS or the RTMP/RTMPS protocol. Objects and data values are serialized into this binary format, which increases performance, allowing applications to load data up to 10 times faster than with text-based formats such as XML or SOAP.

Beneath A Binary Sky is an engine that simulates a world in which robots controlled by programs can live, work, fight, and even bear new children. The long-term goal of the project is to create a fully configurable engine that can simulates any kind of world, from simple to complex ones with many rules and events.

Rejasca is a modern and extensible RPC server for RIAs. It’s written in Python, and it aims to support a large number of programming languages on the client side, with Python and Javascript bindings already available. It comes complete with its own IDL, a flexible security system, and tools for automatic service discovery.

Agnos is a cross-language, cross-platform, lightweight RPC framework with support for passing objects by value or by reference. Agnos is meant to allow programs written in different languages to easily interoperate, by providing the needed bindings (glue-code) and hiding all the details from the programmer. The project essentially serves the same purpose as existing technologies like SOAP, WSDL, CORBA, and others, but takes a minimalistic approach to the issue at hand. Unlike the aforementioned technologies, which tend to require integration with Web servers, using verbose XML-based protocols on top of textual transports (HTTP), often also requiring complex topologies (such as name servers for registering objects, etc.). Agnos is designed to be simple, efficient, and straightforward, allowing for direct communication between two ends using a compact binary protocol.

jRapidRPC is a Java RPC library that allows you to create client-server applications that talk in objects. It is small, fast, and extensible. Its smallness helps you learn how to use the library quickly. jRapidRPC is fast due to its compact size and lack of complexity. Also, it uses the ProtoStuff serializer by default. jRapidRPC's extensibility allows you to can write a new client-server or a new serializer.

Collax Business Server is an all-in-one Linux server for small- and medium-sized businesses. It delivers all the important network services within a heterogeneous business environment for communication, infrastructure, compliance, groupware, and storage, all in a reliable and secure way which is easy to manage. It also provides essential security functions such as firewalling and virus and spam filtering, to protect against hacker attacks, viruses, and unsolicited email messages.

XINS is a technology used to define, create, and
invoke remote APIs. XINS is
specification-oriented. When API specifications
are written (in XML), XINS will transform them to
HTML-based documentation and Java code for both
the client-side and the server-side. The
communication is based on HTTP. XINS competes with
the complex SOAP technology. Main design goals
include simplicity, scalability, and testability.
XINS is not only a specification technology, but
also an application development framework. It
offers transaction logging, unique log
documentation, and active code generation.
